Drilling the ol Kevlar

topic posted Wed, March 5, 2008 - 1:56 PM by  offlineYosh
So when i'm Making Cathedral heads, i was using a hole puncher in a drill press, but the shoot on the side gets full and super heats the bit then blunts the end. Any other suggestions?

    I've gotten pretty fond of a tool I made myself. Basically a foot of all-thread (5/16" would probably be best), with a point on one end, and three flattened areas on the other. Stick it in a drill and push lightly.

      As someone above posted, you don't want to actually drill it - as you've discovered, it just gets messy.
      Running the drill in reverse works wonders :)

        Yeah, you're not getting it. It's not a drill bit in the classic sense, but more like a gian screw that I can power with a drill. Instead of cutting the kevlar, it pushes the threads aside then uses that tension to drive the point in further.

        Before this, I used a pair of scissors (dull ones with a sharp point) to get the hole started.

          I made your threaded tool the other night and tried it and OMG that is the best idea I have ever seen. literally went from a half hour of pushing and bit*hing to three seconds of pull a trigger and direct the point. no effort whatsoever.
